IMPROVEMENT IN wlNDow-SAsHEs.

Specification forming part of Letters Patent No.ll17,041, dated February3K, 1874; application filed November 1, 1873.

To all whom it may concern:

Be it known that I, HIRAM C. BURK, of New Cumberland, in the county ofTuscarawas and State of Ohio, have invented a new and Improved Sash, ofwhich the-followin g is a specification: 1

In the accompanying` drawing, Figure 1 represents a vertical centralsection of my improved sash on the line c c, Fig. 2, showing the methodof sliding and fastening it in the frame; Fig. 2, a horizontal sectionof the same on the line a: x, Fig. 1, and Fig. 3, a detail sideelevation of the grooved window-frame, with-spring-cateh.

Similar letters of reference indicate corresponding parts.

The object of my invention is to improve the window-sashes in such amanner that they slide easily in the frame without rubbing olf thepaint, as in the present sashes, and that they may be quickly andreadily detached for repairs, and conveniently fastened. A

In the drawing, A represents the windowframe, which is provided, insteadof the usual strips for guiding the sashes, with grooves or recesses'a,which are either lined with sheet metal or not, as may bepreferrecl.\The sash I3 has projecting side rails b, of wood, metal, orother suitable material, of which one slides loosely in a groove, b,'ofthe sash, while the other is firmly connected thereto. 'lhe sides ofsash B facing the window-frame A are rounded ott' to produce as littlefriction as possible, and prevent the rubbing o of the paint from theadjoining parts of the frame A. The groove b of the sash does not extendthrough the full length of the same, but leaves a solid part, d, at thelower corner thereof, on which the loose rail b is supported, so that itcannot drop out on hoisting the sash. A hook -shaped projection, e, atthe upper end of loose rail b, serves to lift it out of groove b', sothat the sash may easily be taken out of the windowframe, as therounded-off side offers no obstruction to its detachment. rlhe looserail b may also be made of two hinged pieces, by which the taking out ofthe rail from the sash is more conveniently accomplished. The fixed railb is provided with notches f, into which snaps a projecting catch, g, ofband-spring g', which is suitably applied into a recess, a', of frame A,retaining the sash at any desired position. In this manner the methodsof guiding and fastening the sash are combined, so that the sash may notonly be easily taken off the frame,

but also be furnished at cheaper rates.

As an equivalent for lookin g the sash into any position in the frame, alever arrangement may be employed in the recessed lower crosspiece ofthe sash, instead of the spring-catch g g and notches j' of iixed railb. These levers project into the guide-grooves of the frame, beingfulcrumed at suitable distance from and pivoted to a central button, bythe raising or lowering of which the outer ends of the levers bearagainst the frame, retaining the sash in any desired position by thefriction thereon occasioned by its weight.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The sash B, provided with rounded-off sides,

vand arranged with a fixed rail, b, with notches f, and a loosedetachable rail, b, which slides in grooves b', and rests on the bottomprojection d, for retaining the sash by the springcatch in any position,and detaching it easily from the frame, substantially as set forth.

IHR-AM C. BURK.
